The BigQ davit crane from QCEC features E-Z Turn technology that reduces the amount of force needed to rotate a loaded crane.

“What happens is most cranes get rusty and they’re difficult to turn,” says Jim Creighton, general manager for QCEC.

BigQ cranes ride on a bronze pin bushing and rotate within a Nyloil MDX sleeve. A fold-down boom handle provides added leverage.

Available in powder-coated carbon steel or T304 stainless steel for corrosion resistance, the B10 model can support up to 1,000 pounds while the A20 supports up to 2,000 pounds. Both cranes offer 360-degree rotation and four-position adjustable booms that can be raised or lowered while loaded.

Primarily used for lifting pumps out of wells in wastewater treatment plants, each crane can be quickly disassembled for transportation.

“You only pull a pump every three or six months, so with a portable crane you can put it in a truck and go from location to location,” Creighton says.

The cranes are available with permanently installed floor-mounted pedestal bases, inverted bases that recess into concrete floors or side-wall brackets for industrial applications, as well as dolly-mounted pedestal bases for equipment loading.

When mounted in its HQ300 pedestal base, the A20 crane can be adjusted to provide maximum above-floor hook elevations ranging from 46 to 71 inches (28- to 45-inch reach), 47 to 80 inches (36- to 57-inch reach), 48 to 88 inches (45- to 69-inch reach) and 49 to 97 inches (53- to 81-inch reach). Using the HQ321 recessed base reduces those elevations by 14 inches, while the HQ361 dolly base increases them by 7 inches. With the HQ341 bracket, ranges depend on the height of the base relative to the floor.

The B10 crane, mounted in the HQ311 pedestal base, can be adjusted to provide maximum above-floor hook elevations ranging from 51 to 73 inches (23- to 36-inch reach), 51 to 80 inches (30- to 46-inch reach), 51 to 87 inches (37- to 56-inch reach) and 51 to 94 inches (44- to 66-inch reach). The HQ331 recessed base reduces those elevations by 14 inches, while the HQ371 dolly base increases them by 6 inches. With the HQ351 bracket, ranges depend on the height of the base relative to the floor.

Either crane can be equipped with manual or powered winches. The standard WQ100 manual lifting winch has a 2,000-pound maximum capacity and Weston brake mechanism that automatically engages when the handle is not being cranked. Constructed from carbon steel, the winch has a corrosion-resistant zinc dichromate finish and supports both cable quick-connection and carriage-bolted clamping. 800/959-0232; www.qcec.com.
